The proposed research program is focussed on risk management of geohazards affecting infrastructure. This includes, in Canada, 40,000 km of railway tracks, current and proposed tunnels in Ontario and BC, and mining infrastructure in Ontario. The objective of this research is to pro-actively assess the risks associated with these geohazards so as to optimize site investigation, further define best practices for material property characterisation and continue to lead development of state of the art engineering analysis of the stability and design of these structures. In addition, the risk based approach will help to optimize expenditures on stability improvement / risk reduction measures. The outcomes of the research will positively affect risk management, enhancing public and worker safety, maximizing infrastructure operation and reducing expenses when geohazards do affect the infrastructure. ** The research program will include work on a number of sites involving rail infrastructure (White Canyon, BC; Algoma Central Railway, Ont.), rail and tunnel infrastructure (Heron Bay, Ont.), and mining infrastructure (Sudbury, Timmins, Ontario). The objectives of the program include quantification of material property uncertainty, development of behavioural modelling techniques incorporating variability, development of unified multi-hazard analysis methodology, quantification of design reliability, and development of the risk-consequence approach, based on recent work in South African mining risk management. Examining risk management for these infrastructure types builds on advances being made in individual parts of the industry. ** Students to be recruited to the research program over the next five years, include 3 undergraduate employees, 5 masters and 3 doctoral students. They will work on the most pressing problems associated with geohazards, and will develop a world class skill set including use of state of the art numerical simulation and geotechnical imaging tools. All projects involve working directly with industrial and government research collaborators, including CN Rail, CP, Transport Canada, Quadra FNX, XStrata, Vale and NRCan.**

拟议的研究计划的重点是影响基础设施的地质灾害的风险管理。这包括在加拿大，40，000公里的铁路轨道，在安大略和不列颠哥伦比亚省的现有和拟议的隧道，以及在安大略的采矿基础设施。本研究的目的是积极主动地评估与这些地质灾害相关的风险，以优化现场调查，进一步确定材料特性表征的最佳实践，并继续领导这些结构的稳定性和设计的最先进工程分析的发展。此外，基于风险的方法将有助于优化改善稳定/减少风险措施的支出。研究结果将对风险管理产生积极影响，加强公众和工人的安全，最大限度地提高基础设施的运营，并在地质灾害确实影响基础设施时减少费用。** 该研究计划将包括一些涉及铁路基础设施（白色峡谷，不列颠哥伦比亚省;阿尔戈马中央铁路，安大略省），铁路和隧道基础设施（安大略省苍鹭湾），和采矿基础设施（萨德伯里，蒂明斯，安大略）。该计划的目标包括量化材料属性的不确定性，发展行为建模技术，包括可变性，统一的多危害分析方法的发展，量化设计的可靠性，和发展的风险后果的方法，在南非采矿风险管理的基础上，最近的工作。检查这些基础设施类型的风险管理是建立在该行业各个部分所取得的进步之上的。** 未来五年将招收的研究生包括3名本科生，5名硕士生和3名博士生。他们将致力于与地质灾害相关的最紧迫的问题，并将开发一套世界一流的技能，包括使用最先进的数值模拟和岩土成像工具。所有项目都涉及直接与工业和政府研究合作伙伴合作，包括CN Rail，CP，加拿大交通部，Quadra FNX，XStrata，Vale和NRCan。
